Comment 0 for bug 1467691

Suspend to RAM fails to wake up on my HP dc7800p. After suspending with pm-suspend an attempt to wake the machine up with the power button leads to a black screen. The video card does not appear to show any activity to my monitor. I must hold the power button down for 6 seconds to power off and boot the system back up.

This system is using the on-board intel graphics. If I put an nvidia card into the machine it is able to suspend and resume without issue.
